ROLLING-DOOR HANGER.

Specification of Letters Patent.

Application filed July 17, 1905. Serial No. 270,284.

Patented Aug. 6, 1907.

To a 'llimifl it may concern:

le it known that l, Mnxrox E. IlL'NT, a citizen of the tflnitcd States. residing at \\'aterville. inthe county of Kcn'ncbec and State of Maine,'have invented a new and useful Rolling-Door llanger, of which the following is aspecilication.

This invention relates to improvements in rolling door hangers and one of the objects is to provide means for adjusting the door longitudinally or vertically with relation to the hanger so as. to cause the lower,edge thereof to be brought to the proper position where it will neither bind, by reason of being too long, nor present a cracker space at the. bottom by reason of being too short; thus obviating the necessity of cutting off the door or oi changing the position of the hanger.

Another objer't is to provide means for adjusting the door laterally so as to throw it away from or toward the building without changing its support or affecting its operation thereon.

With these and other objects in view the invention consists in the construction, combination and operative aggronpment of parts, all as will be-described hereinafter, illustratedin the accompanying drawings and tin-ally pointed out in the appended claims. I

In the drawings:Figure l is a front elevation of my improved hanger applied to the door. Fig 2 is an end elevation thereof with the track or support shown in section. Fig. 3 is a detail in elevation of the roller, and Fig. 4 is a vertical transverse section thereof.

Making renewed reference to the drawings, wherein like character of notation indicate corresponding parts throughout the several views, A designates a portion of the sliding or rolling door and k designates a suitable support or track designed to be secured in any suitable way to the building above the door.

The hanger frame as a whole is designated u and consists of a plate bent at its upper end, as at a, to provide a'casing or housing for the roller, and at its lower end it is cut away or slotted longitudinally, at a, a portion oi the metal so cut away being bent outwardly to form an outstanding car f. Upon each side of the central slot at are smaller longitudinal slots (I through which bolts I extend. These bolts are preferably driven through the door from the side opposite the plate a so that the threaded ends will receive elamping nuts l which engage the outer face of the plate adjacent to the slots, the plate being permitted to be moved longitudinall'y or vertically on the door when the nuts are released from binding engagement therewith. as will be obvious.

Secured to the door in the cut away portion of the hanger o is a bracket b having an outstanding car 9 in vertical alinement with the earfol' the plate a but .separated thereirom. Loosely mounted in an aperture in the ear g is an adjusting rod i: having a collar 0 on the lower end thereof and having its upper end threaded into a threaded aperture in the ear et the plate and. thus when a wrench is applied to the angular end 0 of the adjusting bolt and the latter rotated. plre a will follow up and down on the rod 0 and thereby iidjust the bracket vertically with relation to the door on which it is slidably mounted.

, The roller for the hanger is mounted in the upper end of the plate a between its face and its bent end a upon a shalt i which is fixed against rotation in said parts and is prel'erably provided with a flat face to key the hub member of the roller thereon. This hub member m is shown in Figs. 3 and 4, as consisting of two parts separable longitudinally, but held together by. means of screws o.' The periphery of the two part hub is formed with a groove to constitute a bearing for the balls r which are arranged circumterentially therearound. Revolubly mounted upon these balls is a ring It, the inner periphery 01' which is provided with a groove coincident with the groove of the hub and the outer periphery of which is also provided with a groove or guide-way s for the supporting track 1*. which fits into said groove, as shown in Fig. 2. I

From the description thus largiven, it will be seen that the roller is provided with a ball bearing which is interposed between the revoluble ring or rim and the two part hub, which is rigidly secured or keyed to a non-rotatable shaft and thus when the door is moved the ring member h is the only element that rotates. It will also be seen that the two part hub facilitates the introduction and removal or the balls and the assembling and separation of the parts, it being'unders tood that new balls may be inserted by removing the screws 0 and sliding one of the parts of the hub longitudinally uponthe shalt, 1'.

After the hanger has been applied to the door it is often found that the door is too close to the building or too far away from the same, and thus the necessity of providing a lateral adjustment therefor. In my present invention I am able to adjust the door so as to position it nearer to or further away from t 9 building without removing any of the parts of the hanger or the supporting track k. This adjustment is effected by providing the two part huh m witlra threaded aperture which ,is let a threaded adjusting screw j the end of which is swiveled in the plate a oi the door, any suitable swiveling means being employed, but, as shown in the drawings, I prefer to have the head of said screw provided with an annular groove in which the end of the pin n engages, the pin being secured to the plate by staples or other fastening devices 17/, as shown in Figs. 1 and 2 and the end of the screw preferably having means for rotating it in the plate.

rying the screw will move laterally and the shaft i will slide through the hub which, being .fiXOd with relation tothe rim and track, causes the entire hanger to be moved transversely of the supporting track k, there by adjusting the door relatively to the wall of a building.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a door hanger, the combination \vith the hanger member and a supporting track, of a shaft connected to said hanger member, a hub member secured to the shaft. a ring revolubly mounted upon the hub member, bearing elements between the hub and ring. and means whereby the hanger and door may be adjusted laterally of the track.

2, In a door hanger, thecombination with the hanger member and a supporting track; of a roller carried by the hanger and provided with a non-rotatable hub; and rotatable means mounted in the hanger member and engaging said hub to adjust the hanger and door laterally of the track.

'3. In a door hanger the combination with the hanger member bent upon itself at its upper end, and a supporting track; ofn 'roller carried by th hanger member between its body and bent portion and provided with a non-rotatable hub, and neans nionntcd in the hanger member and engaging said hub to adjust: the hanger and door laiorally oi the track. t

4. In a rolling door banner, the mnibination with a hanger member and a supporting travk; ot a roller earried by the hanger member and provided with a nona'ota' table hub; an adjusting screw swivoled in the hanger member and baringthreaded engagenlvnt with the hub of the roller. whereby the hanger member and door may be adjusted laterally relatively to the track.

In a door banger, the combination with the hanu 'r member and a supporting; traek. of a shaft lixod in tl hanger member, a hub lllt'llllHl' l\'t- 't l to said -hatt. a ring revolubly mounted upon said hub tot-tuberv a ball beariue between the hub and the ring. and an adios-tine st'l'i-n' swiveled in the lianeor member Illltl having lhl't'atltti rueagmnent with the hub number.
